Description

Technical Field

[0001] This invention relates to the field of automated cutting and processing production line equipment, specifically to a fully automated roll laser processing production line and a method for processing roll materials. Background Technology

[0002] With the rapid development of industries such as textile machinery, grain machinery, medical machinery, lighting decoration, packaging, shipbuilding, automobiles, aviation, and steel, flatbed laser cutting technology has also undergone significant changes. In particular, the continuous updates in coil cutting technology in the past two years have led to a continuous increase in the research and development demand for flat metal products in industrial production. Currently, flatbed laser cutting equipment is gradually becoming automated. Coil laser cutting machines are mainly suitable for the precision cutting of thin metal coils such as stainless steel, carbon steel, manganese steel, galvanized sheets, various alloy sheets, and rare metals. The semi-finished products produced are widely used in industries such as metal crafts, hardware products, sheet metal processing, auto parts, chassis, cabinets, eyeglasses, jewelry, electronics, advertising signage, and kitchen and bathroom products.

[0003] The coil laser cutting equipment on the market processes different types of sheets depending on their intended use. Common coil laser cutting equipment is usually an ordinary flatbed cutting machine with an additional uncoiling and feeding device and a corresponding control system to achieve automation. However, the unloading mode is always manual sorting and unloading. This method cannot meet the production volume requirements of products that require high sheet processing precision, such as kitchenware, eyeglasses, cabinets, and chassis. Furthermore, for some high-requirement products, there is no protection for the processed sheets, which fails to meet the product quality requirements.

[0004] A patent application with publication number CN109940405A discloses a moving coil laser cutting production line for sheet metal, comprising a loading trolley, an uncoiler, a leveler, and a cutting machine arranged sequentially adjacent to each other. The cutting machine includes a worktable, a guiding mechanism, a feeding mechanism, a cutting mechanism, a pressing mechanism, and a discharging mechanism. The guiding mechanism is located on the side of the worktable facing the leveler, and the feeding mechanism is connected to the middle of the worktable. The feeding mechanism includes an upper feeding roller, a lower feeding roller, a transmission shaft, a drive motor, a pair of fixed vertical plates, and a pair of adjusting cylinders. The pair of fixed vertical plates are both vertically arranged and fixedly connected to both sides of the middle of the worktable. This production line only has a loading device and lacks a sorting and unloading device, resulting in low efficiency in processing sheet metal. Furthermore, the sheet metal surface is not protected during processing, making it prone to scratches and failing to meet the surface quality requirements of the processor. Summary of the Invention

[0005] One of the objectives of this invention is to provide a fully automated roll material laser processing production line, which solves the problems of low efficiency and the need for manual assistance in the process of laser cutting machine processing of roll materials.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0007] A fully automated roll-to-roll laser processing production line includes an unwinding machine, a straightening and coating integrated machine, and a laser cutting machine arranged in sequence. It also includes a material unloading and sorting machine and an alternating material receiving platform. The material unloading and sorting machine is located above the laser cutting machine, and the alternating material receiving platform is located on one side of the material unloading and sorting machine.

[0008] Furthermore, the unwinding machine includes an unwinding roller and an unwinding frame. The unwinding roller is rotatably connected to the unwinding frame. The unwinding roller includes a roller core, a support plate, and a slider. The support plate is movably connected to the roller core. The slider is disposed between the roller core and the support plate. The slider can slide along the axial direction of the roller core. The slider can lift the support plate in a direction perpendicular to the roller core, which can unwind the coil and facilitate changing the coil.

[0009] Preferably, the integrated straightening and coating machine includes a frame, a feeding platform, a lower pressure roller, an upper pressure roller, a coating roller, and a directional roller. The feeding platform is located at one end of the frame and faces the unwinding machine. The lower pressure roller and the upper pressure roller are respectively positioned to abut against the two ends of the roll material and are located behind the feeding platform. The coating roller is located behind the lower pressure roller, and the directional roller is perpendicular to the roll material and located behind the coating roller. This machine is used to straighten the plane of the roll material, adjust its direction, and coat it with film. This ensures the flatness of the roll material when it enters the laser cutting machine for processing, improves the accuracy of processing the roll material, and enhances the surface quality of the semi-finished product.

[0010] Preferably, the device also includes an anti-wrinkle roller and a feeding table. The anti-wrinkle roller is movably connected to the other end of the frame and abuts against the surface of the roll material. The feeding table is located at the other end of the frame, below the anti-wrinkle roller, and flush with the feeding direction of the roll material.

[0011] As an even better option, an automatic winding device is also included. The automatic winding device is located on one side of the unwinding machine. The automatic winding device includes a feed chute and a slide. The feed chute is located on the slide, and the slide is slidably connected to the unwinding frame. It can move parallel to the axial direction of the unwinding roller, so that the roll material can be quickly replaced after it is exhausted, shortening the material replacement interval and improving the efficiency of the fully automatic roll material laser processing.

[0012] Preferably, the laser cutting machine includes a laser cutting head and a bed. The laser cutting head can move on the bed. The bed includes multiple support teeth, a first chain, and a material changing section. The material changing section is connected to the rear of the bed along the direction of material movement. The multiple support teeth are connected to the first chain along the width direction of the bed. The machine can perform laser cutting on the material roll. After processing, the semi-finished product is conveyed to the material changing section and then transferred away by the unloading and sorting machine, which meets the requirements of continuous production and improves the utilization rate of the laser cutting machine.

[0013] Preferably, the unloading and sorting machine is positioned above the material changing section. The unloading and sorting machine includes a first support leg, a second support leg, a crossbeam, a first sorting arm, a second sorting arm, and a gripper. The crossbeam is mounted on the first and second support legs. The first sorting arm is slidably connected to the crossbeam, and the second sorting arm is slidably connected to the first sorting arm. The first and second sorting arms are perpendicular to each other. The gripper is positioned at one end of the second sorting arm and faces the direction of the rolled material. It can transfer the material processed by the laser cutting machine to the adjacent alternating support platform. In conjunction with the multiple support teeth that can circulate on the material changing section, it can continuously transport materials to meet the requirements of the fully automatic rolled material laser processing production line.

[0014] Preferably, the alternating material receiving platform is located below the material unloading and sorting machine. The alternating material receiving platform includes a first material receiving platform, a second material receiving platform, a base frame, and a drive mechanism. The first material receiving platform is slidably connected to the base frame, and the second material receiving platform is slidably connected to the base frame. The second material receiving platform is located below the first material receiving platform. The drive mechanism is located at one end of the base frame. The first material receiving platform and the second material receiving platform move alternately under the drive mechanism to separately place the laser-cut materials. It can continuously receive materials from the laser cutting machine to realize continuous unloading of semi-finished products.

[0015] Even better, a waste disposal area is also included, located behind the laser cutting machine, for placing waste materials generated during the laser cutting process, which are then transported away by external logistics equipment, ensuring the continuous operation of the fully automated laser processing production line.

[0016] The second objective of this invention is to provide a method for processing roll materials, which solves the problems of low efficiency and the need for manual assistance in the process of laser cutting machine processing roll materials.

[0017] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0018] A method for processing roll materials, implemented by the aforementioned fully automated roll material laser processing production line, includes the following steps:

[0019] S1. Unwinding: The roll of material is mounted onto the unwinding machine, and one end of the roll of material is inserted into the straightening and coating integrated machine;

[0020] S2. Pre-processing: The integrated straightening and coating machine straightens and coats the roll material, and then conveys the roll material to the laser cutting machine;

[0021] S3. Cutting process: The laser cutting machine cuts the roll material, and after the cutting process is completed, the entire roll material is conveyed to the bottom of the unloading and sorting machine;

[0022] S4. Sorting: The unloading sorting machine sorts the semi-finished products of the roll material into categories and places them onto the alternating material receiving platform, while the bed of the laser cutting machine moves to discard waste material;

[0023] S5. Unloading: The alternating support platform moves back and forth in the direction of the laser cutting machine to transfer the processed semi-finished product out, which is then taken away by external logistics equipment, realizing the continuous cutting processing of the roll material.

[0024] The beneficial effects of this invention are as follows:

[0025] (1) The fully automatic roll material laser processing production line has a correction and coating integrated machine. Before cutting the roll material, it can be leveled and aligned so that the position is accurate when it enters the laser cutting machine for cutting, which improves the cutting accuracy of the roll material, reduces the generation of waste, and can also coat the cut surface of the roll material for protection, so that the roll material will not be scratched during cutting and moving, thus meeting the needs of high precision products.

[0026] (2) The fully automatic roll laser processing production line has a material sorting machine and an alternating material support platform. With the support teeth on the laser cutting machine that can move in a cycle, it can continuously transport the finished roll material to the outside, separate the waste generated by cutting, and classify different types of cut parts. It can realize the production of materials in a fully automated manner, which improves the utilization efficiency of materials and the processing efficiency of roll material.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figures 1-10 As shown, a fully automatic roll-to-roll laser processing production line includes an unwinding machine 1, a straightening and coating integrated machine 3, a laser cutting machine 4, a material unloading and sorting machine 5, and an alternating material receiving table 6 arranged in a straight line. The material unloading and sorting machine 5 is located above the laser cutting machine 4, and the alternating material receiving table 6 is located on one side of the material unloading and sorting machine 5 and within the stroke range of the material unloading and sorting machine 5. The material unloading and sorting machine 5 circulates between the laser cutting machine 4 and the alternating material receiving table 6, classifying and placing the semi-finished products 8 of the laser cutting machine 4 onto the alternating material receiving table 6.

[0042] Preferably, the unwinding machine 1 includes an unwinding roller 11, an unwinding frame 12, and a motor. The unwinding roller 11 is rotatably connected to the unwinding frame 12. The motor drives the unwinding roller 11 to rotate. The unwinding roller 11 includes a roller core 111, a support plate 112, and a slider 113. The support plate 112 is movably connected to the roller core 111. The slider 113 is disposed between the roller core 111 and the support plate 112. The slider 113 can slide along the axial direction of the roller core 111. The slider 113 is wedge-shaped. The bottom surface of the support plate 112 facing the roller core 111 also has an inclined surface. The inclined surfaces of the two are engaged. By sliding the slider 113, the support plate 112 can be lifted in a direction perpendicular to the roller core 111 to fix the coil 9. The coil 9 can be locked along its center to prevent the coil 9 from shaking during unwinding and to facilitate coil changing.

[0043] Preferably, the unwinding machine 1 is also provided with a pressure roller 13, which is rotatably connected to the unwinding frame 12. The pressure roller 13 is elastic and can move toward the surface of the coil 9. When the unwinding roller 11 is used, it presses down on the coil 9 to prevent the rotating coil surface from wrinkling and stacking, thereby improving the stability of unwinding.

[0044] Furthermore, the straightening and coating integrated machine 3 includes a frame 31, a loading platform 32, a lower pressure roller 33, an upper pressure roller 34, a coating roller 35, and a directional roller 39. The loading platform 32 is located at one end of the frame 31 and is curved towards the unwinding machine 1 to prevent wrinkles in the roll 9 when receiving it. The lower pressure roller 33 and the upper pressure roller 34 are respectively located on the upper and lower end faces of the roll and are behind the loading platform 32. Multiple lower pressure rollers 33 and multiple upper pressure rollers 34 are arranged along the moving direction of the roll 9. The lower pressure rollers 33 and the upper pressure rollers 34 contact the end faces of the roll 9 respectively to flatten the roll 9 by roller pressing and prevent laser cutting. Unevenness of the roll material 9 during processing leads to defective products. To improve the yield of laser cutting, the roll material 9 is also powered to feed the laser cutting machine 4. The coating roller 35 is located behind the lower pressure roller 33 and covers the leveled roll material 9 with a protective film to prevent scratches on the surface of the roll material 9. The directional roller 39 is perpendicular to the roll material 9 and is located behind the coating roller 35 and on the loading table 32. It can correct the direction of the roll material 9 entering and exiting the correction and coating integrated machine 3. The directional roller 39 includes two vertical rollers and is located on both sides of the roll material 9. The distance between the two vertical rollers can be adjusted by handwheel to guide the roll material entering the correction and coating integrated machine 3.

[0045] Preferably, the straightening and coating integrated machine 3 is also equipped with an anti-wrinkle roller 36 and a feeding table 37. The anti-wrinkle roller 36 is movably connected to the other end of the frame 31 and abuts against the upper surface of the roll material 9 under pressure, so that the roll material 9 after straightening and coating will not wrinkle during the process of entering the laser cutting machine 4. The feeding table 37 is set at the other end of the frame 31 and is flush with the incoming direction of the roll material 9. The feeding table 37 is equipped with multiple rollers to ensure that the roll material 9 can be wound into the laser cutting machine 4 for processing in a flat state.

[0046] Preferably, a connecting rod 38 is provided between the straightening and coating integrated machine 3 and the unwinding machine 1. One end of the connecting rod 38 is fixed to the bottom of the unwinding frame 12, and the other end is fixed to the bottom of the frame 31, so that the straightening and coating integrated machine 3 and the unwinding machine 1 are stably connected together, so that the roll material 9 output by the unwinding machine 1 can stably enter the straightening and coating integrated machine 3, thereby improving the stability of the movement of the roll material 9.

[0047] Preferably, the laser cutting machine 4 includes a laser cutting head 41 and a bed 42. The laser cutting head 41 can move on the bed 42 to cut the roll material 9. The bed 42 includes multiple support teeth 421, a first chain 422, and a material changing section 424. The material changing section 424 is connected to the rear of the bed 42 along the direction of movement of the roll material. The multiple support teeth 421 are connected to the first chain 422 along the width direction of the bed 42. The first chain 422 is arranged along the length direction of the bed 42 and runs through the entire bed 42. It can drive the multiple support teeth 421 on the bed 42 to form a platform for laser cutting the roll material. Driven by the first chain 422, the multiple support teeth 421 can convey the roll material 9 on the platform backward until it is picked up by the unloading and sorting machine 5. The remaining waste tail material falls into the waste area 7 under the action of gravity and inertia, realizing the uninterrupted cutting processing of the laser cutting machine 4.

[0048] Preferably, the laser cutting machine 4 is equipped with a dust removal device 423, which includes a dust suction chamber and an exhaust pipe below the support teeth 421. The dust removal device 423 is used to collect and treat the smoke and slag during the laser cutting process, reduce environmental pollution, ensure that the production line is not affected by smoke and dust, and enable the laser cutting machine 4 to operate stably for a long time.

[0049] Preferably, anti-scratch linings 435 are provided on both sides of the material changing section 424. The anti-scratch linings 435 are composed of universal balls and a base plate. Multiple universal balls are installed on the base plate at equal intervals along the length of the material changing section 424. The base plate is fixed on both sides of the material changing section 424. The anti-scratch linings 435 are higher than the support teeth 421. When the semi-finished product 8 slides out of the material changing section 424, it can support the semi-finished product 8 and prevent it from blocking the circulation movement of the support teeth 421, thereby preventing material jamming. It can also stably discharge the waste tail material from the material changing section 424 and ensure the stable operation of material discharge.

[0050] Preferably, the unloading sorting machine 5 is located above the material changing section 424. The unloading sorting machine 5 includes a first support leg 51, a second support leg 52, a crossbeam 53, a first sorting arm 54, a second sorting arm 55, and a gripper 56. The crossbeam 53 is mounted on the first support leg 51 and the second support leg 52, with one end fixedly connected to the upper end of the first support leg 51 and the other end fixedly connected to the upper end of the second support leg 52. The first support leg 51 is U-shaped, with its lower end fixed to the ground. The second support leg 52 is U-shaped, with the side of the notch facing the side of the crossbeam 53, allowing the gripper 56 to pass through the notch into the second support leg 52, thereby facilitating the material changing section 424 and the alternating material receiving platform 6. The upper part moves to achieve the sorting of semi-finished products 8. The first sorting arm 54 is slidably connected to the crossbeam 53, which can drive the gripper 56 to move between the material changing section 424 and the alternating material receiving platform 6. The second sorting arm 55 is slidably connected to the first sorting arm 54. The second sorting arm 55 is arranged perpendicular to the ground. The first sorting arm 54 and the second sorting arm 55 are perpendicular to each other, which can raise and lower the gripper 56. The gripper 56 is used to pick up materials on the material changing section 424 and put materials on the alternating material receiving platform 6. The gripper 56 is set on one end of the second sorting arm 55 and faces the direction of the rolled material. The gripper 56 adopts a combined frame structure, and its length is close to the width of the material changing section 424. It is used to carry semi-finished products 8 of various sizes.

[0051] Preferably, the gripper 56 is provided with multiple suction cups 57, which are slidably connected to the gripper 56. Their positions can be adjusted by sliding on the gripper 56. The multiple suction cups 57 can be freely combined according to the different shapes of the materials to be gripped, and the shape can be matched with the materials to meet the requirements of gripping different materials, so that the production line can adapt to the production of materials of different specifications and shapes.

[0052] Preferably, the alternating support platform 6 is located below the unloading and sorting machine 5. The alternating support platform 6 includes a first support platform 61, a second support platform 62, a base frame, and a drive mechanism 65. The first support platform 61 is slidably connected to the base frame, and the second support platform 62 is slidably connected to the base frame. The second support platform 62 is located below the first support platform 61. The drive mechanism 65 is located at one end of the base frame. The drive mechanism 65 includes a sprocket 651, a second chain 652, and an RV geared motor. The RV geared motor drives the sprocket 651, which in turn drives the second chain 652 to move cyclically along the base frame. The first support platform 61 and the second support platform 62 move alternately under the drive of the drive mechanism 65, continuously conveying the semi-finished product 8, which is then removed by external logistics equipment to achieve uninterrupted unloading.

[0053] Preferably, the alternating support platform 6 further includes two first guide rails 63, two second guide rails 64, a first connecting rod 611, a second connecting rod 621, multiple first guide wheels 612, and multiple second guide wheels 622. The two first guide rails 63 are symmetrically installed along the centerline of the bottom frame. The multiple first guide wheels 612 are installed below the first support platform 61, and the first guide wheels 612 can roll on the first guide rails 63. The second guide wheels 622 can roll on the second guide rails 64. The first connecting rod 611 is installed on the lower side of the first support platform 61, with one end connected to the first support platform 61 and the other end fixed to the upper chain of the second chain 652. The linear movement of the second chain 652 drives the first support platform 61 towards... The material changing section 424 reciprocates. The second connecting rod 621 is installed on the lower side of the second material receiving platform 62. One end of the rod is connected to the second material receiving platform 62, and the other end is connected to the lower chain of the second chain 652. The second chain 652 drives the second material receiving platform 62 to reciprocate towards the material changing section 424. Since the upper and lower chains of the second chain 652 move in opposite directions but at the same speed, the first material receiving platform 61 and the second material receiving platform 62 can alternately receive the semi-finished products 8 from the laser cutting machine 4, realizing the continuous feeding and classification of the semi-finished products 8 by the production line. The side of the alternating material receiving platform 6 that is not opposite to the laser cutting machine 4 can be connected to an external logistics trolley to continuously transport the semi-finished products 8 outward.

[0054] Preferably, the second receiving platform 62 is provided with multiple baffles 623. The baffles 623 are vertical and arranged close to the edge of the second receiving platform 62 to prevent the finished product 8 from slipping off after being placed on the second receiving platform 62. Since the second receiving platform 62 is located below the first receiving platform 61, the baffles 623 play a role in preventing the second receiving platform 62 from interfering with the first receiving platform 61.

[0055] Preferably, the fully automatic laser roll material processing production line is also equipped with an automatic winding device 2. The automatic winding device 2 is located on one side of the unwinding machine 1. The automatic winding device 2 includes a feeding trough 21 and a slide 22. The feeding trough 21 is located on the slide 22 and has a groove with a trapezoidal cross-section. The roll material is put into the groove from the outside, so that the center of the roll material is aligned with the center of the unwinding roller 11. The slide 22 is slidably connected to the unwinding frame 12 and is located on one side of the unwinding frame 12. It can move parallel to the axial direction of the unwinding roller 11. The roll material in the feeding trough 21 can be pushed onto the unwinding roller 11 by the slide 22. The unwinding roller 11 holds the roll material and realizes rapid winding, which improves the processing efficiency of the production line.

[0056] Preferably, the fully automatic laser coil processing production line is also equipped with a waste area 7, which is located behind the laser cutting machine 4. The waste area 7 is equipped with a material frame, which is located below the end of the material changing section 424. The waste tail material from the material changing section 424 is dislodged from the bed 42 by the rotating support teeth 421 under the action of inertia and falls into the material frame. When the material frame is filled, it is transported away by an external conveyor trolley and an empty material frame is put in, so as to realize the continuous processing of waste tail material, ensure that the production line can operate without interruption, and improve the production efficiency of coil laser cutting processing.

[0057] Preferably, the operation of the fully automated laser roll material processing production line is controlled by a control system. The control system can control each component and integrates a protection system 10. It can be linked with an external central processing system and matched with the entire product line production to maximize production efficiency.

[0058] Preferably, the fully automated laser roll forming production line is also equipped with a protection system 10. The protection system 10 is arranged around the fully automated laser processing production line and includes guardrails and safety light curtains. The guardrails are arranged along the transverse and longitudinal directions of the production line, partially surrounding the production line, with openings only on the sides of the unwinding machine 1, laser cutting machine 4, and alternating material receiving table 6. Safety light curtains are arranged in the openings and are connected to the control system. During the operation of the production line, when foreign objects or human bodies are detected, feedback is sent to the control system to remind the operators and to stop the production line in an emergency, preventing injury to personnel and damage to the production line, thereby improving the stability of the production line operation and the safety of the operators.

[0059] A method for processing rolled materials specifically includes the following steps:

[0060] S1. Unwinding: The roll material is installed on the unwinding machine 1, and one end of the roll material 9 is inserted into the straightening and laminating machine 3;

[0061] S2. Pre-treatment: The straightening and coating integrated machine 3 straightens and coats the surface of the roll 9, and then conveys the roll 9 to the laser cutting machine 4;

[0062] S3. Cutting process: The laser cutting machine 4 cuts the coil material 9. After the cutting process is completed, the coil material 9 is transported to the bottom of the unloading and sorting machine 5.

[0063] S4. Sorting: The unloading sorting machine 5 sorts the semi-finished products of the roll material 9 and places them separately on the alternating receiving table 6. The bed of the laser cutting machine 4 moves to throw off the waste material.

[0064] S5. Unloading: The alternating support table 6 moves back and forth in the direction of the laser cutting machine 4 to transfer the processed semi-finished products out, which are then taken away by external logistics equipment, realizing the continuous cutting processing of the coil material 9.

[0065] The detailed working process of this fully automated roll-to-roll laser processing production line is as follows:

[0066] The roll material 9 is transported by a logistics vehicle to the automatic winding device 2, where it is carried by the feed trough 21. Driven by the slide 22, the feed trough 21 moves towards the unwinding roller 11, causing the unwinding roller 11 to enter the center hole of the roll material 9. The slider 113 then lifts the support plate 112 until it is fully supported and locked in the center hole of the roll material 9. The feed trough 21 exits the unwinding machine 1, and the roll material 9 is unwound, with one end fed through the loading table 32 into the straightening and coating integrated machine 3. There, it is pressed by the lower pressure roller 33 and upper pressure roller 34, and controlled by the control... The control system starts the unwinding machine 1 and the straightening and laminating machine 3, feeding the roll material 9 onto the bed 42 of the laser cutting machine 4. As the roll material 9 passes through the straightening and laminating machine 3, it is sequentially straightened by the lower pressure roller 33 and the upper pressure roller 34, then laminated by the laminating roller 35, and finally exits from the feeding table 37. The direction is adjusted by the directional roller 39 when entering and exiting the straightening and laminating machine 3. After the roll material 9 enters the bed 42 of the laser cutting machine 4, the feeding stops under the control of the control system, and the laser cutting machine 4 is started. The laser cutting head 41 then cuts the roll material 9. After a period of time, the processing of the coil 9 is completed. The platform composed of support teeth 421 moves under the drive of the first chain 422, moving the semi-finished product 8 on it to the material changing section 424. The unloading and sorting machine 5 starts, and the first sorting arm 54 moves the gripper 56 to above the material changing section 424. Then, the second sorting arm 55 moves the gripper 56 down, and the suction cup 57 on the gripper 56 picks up the semi-finished product 8. Then, the first sorting arm 54 and the second sorting arm 55 move the semi-finished product 8 on the gripper 56 to the alternating material receiving platform 6. For semi-finished products of different specifications and shapes, the unloading... The sorting machine 5 is placed on the first receiving platform 61 or the second receiving platform 62 respectively. The first receiving platform 61 and the second receiving platform 62 continuously convey the semi-finished product 8 outward in an alternating manner. In addition, the waste tailings left after the laser cutting machine 4 cuts the roll material 9 move towards the waste area 7 under the drive of the support teeth 421 and fall off under its own inertia and gravity. The support teeth 421 rotates in a cycle, continuously sending the semi-finished product 8 and the waste tailings out of the processing area of ​​the laser cutting machine 4. The above process runs in a cycle, which can realize the full automation of the laser cutting processing of the roll material 9.

[0067] Example 2

[0068] The same features as those shown in Embodiment 1 will not be repeated here. The difference is that the alternating material receiving platform 6 is further provided with a third material receiving platform and a fourth material receiving platform. The third and fourth material receiving platforms have the same structure as the first material receiving platform 61 and the second material receiving platform 62, and are located above the first and second material receiving platforms. They are used to classify and transport semi-finished products 8 or waste materials. In addition, the material receiving platform can provide storage space for storing semi-finished products 8 and buffer them to ensure the stable operation of laser cutting of coil material 9 for a long time. It can also meet the needs of classifying more types of semi-finished products 8, making it convenient for external logistics equipment to rotate and improving the efficiency of unloading semi-finished products 8.
